All aboard! Let’s take a ride on the world’s highest railway—the Qinghai-Tibet Railway（青藏铁路）. Sit back and enjoy the journey. Get ready for the trip of a lifetime.
We’re leaving Qinghai Station. The scenery along the way is some of the wildest in all of China. Keep your eyes open as we race through this beautiful land. You might see a rare Tibetan antelope（藏羚羊）from your window.
Before we begin our journey, let’s learn about this amazing railway. It’s truly one of the great engineering wonders of the 21st century. When it was completed on July 1, 2006, the Tibet Railway set nine world records, including the world’s highest railway at 5,072 metres above sea level, the world’s highest tunnel（隧道）at 4,905 metres, and the longest tunnel ever built on permafrost（冻土）.
As we travel higher, the air gets thinner and thinner. Soon there will only be 50 to 60 percent of the oxygen which we are used to breathing. But don’t be afraid. Each rail car has two separate oxygen systems. One system spreads oxygen throughout the train at all times. And each passenger can also get a personal oxygen mask just like those used in planes.
Here are a few more things to think about as our train leaves the station. The designers solved three main challenges when building this great railway. First, the high altitude（海拔）made the task difficult because there was no enough oxygen. Second, much of the railway runs across permafrost, a type of ground that keeps changing as the weather warms and cools. Finally, the railway goes through some of the most sensitive ecology（敏感的生态环境）in China. Great care was necessary to make sure of the smallest possible influence on nature.
All three challenges were met, making our trip possible. All aboard! The train to Tibet is leaving in fifteen minutes.

Barbara was driving her six-year-old son, Benjamin, to his piano lesson. They were late. There was always so much to do, and Barbara, a night-duty nurse at the local hospital, had recently worked extra hours. She was tired.
“Mom!” Ben cried. “Look!” Just ahead, a car had lost control (控制) on the icy road and wildly rolled over, and then crashed (撞) into a telephone pole. Barbara went over. Thank goodness she was a nurse — she might be able to help these unfortunate passengers. Then she stopped. What about Ben? She couldn’t take him with her. Little boys shouldn’t see scenes (场面) like this one. But was it safe to leave him alone?
For a little moment Barbara thought of going on her way. Someone else was sure to come along. No! “Ben, honey, promise me you’ll stay in the car!” “I will, Mommy,” he said as she ran.
Two girls of high school age were in the car. One was dead and the driver was still breathing. But if help came soon, the girl would live.
A trucker had pulled up and was calling for help on his cell phone. Soon Barbara heard the ambulance sirens (救护车汽笛).

It’s three thirty in the afternoon at Raynham Primary School in London. Students are ready for their after-school math lesson. Thousands of kilometers away, their math tutors are also arriving for class. Each pupil gets an online tutor. The students work on their computer screen and wear a headset (耳机) to talk to their tutor.
Their classroom teacher, Altus, says he has seen an improvement in results. Nine-year-old Samia says she enjoys the online lessons. She said, “It helps me because sometimes when we’re doing it in class, I don’t hear the teacher very much and I don’t understand, but online is better.”

Expert(专家) say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger (手指)with his eyes still closed, asking for one more minute to sleep. Like thousands of students “ early birds” in China, he has to get up before six every morning.
A report shows that without a good night’s sleep, students seem to be weaker than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
Experts have ever said that the students should develop good study habits. So some clever students never study late, they are able to work well in class.The 10-year-old boy asked for more minute to sleep because__________

When you wake up every day, once again to see this beautiful world, when your parents, teachers and friends give you help, will you know how to be （71）grateful? And when you feel unlucky and make mistakes, will you still be thankful?
Yu Dan, a professor at the Beijing Normal University, made a report about Gratitude Education（感恩教育）．It will affect Chinese people, especially the teenagers．
Nowadays, some teenagers only care about things outside．They often behave badly．For example, they fight each other, use phones in class, be rude to their parents and teachers and so on．Most of them don’t know love, respect and gratefulness．
Being grateful or thankful is very important．（73） It is impossible for anyone to be lucky and successful all the time as long as he lives in the world．We should learn how to face failure or bad luck bravely and to try to deal with it．As we know, “Life is a mirror．When you smile in front of it, it will also smile and so will it when you cry to it．” If you are grateful to life, it will bring you shining sunlight．If you always complain about everything, you may own nothing in the end．
I think the teenagers should be grateful to life even when we are unsuccessful or unlucky．We have many reasons for being grateful．For example, being grateful is a way to communicate with adults．And it is a way to sing for our life which comes just from our love and hope．
If each of us has an attitude of being grateful, we’ll lead a better and more beautiful life．So remember, being grateful forever．
